Japan Professional Football League Optimizes Match Scheduling With ILOG Constraint Programming

ILOG Technology Radically Shortens Scheduling Time from Three Weeks to One Day SUNNYVALE, Calif., May 28 /PRNewswire-FirstCall/ -- ILOG(R) (Nasdaq:ILOG; Euronext: ILO; ISIN: FR0004042364) announced today that JapanProfessional Football League, J. LEAGUE, utilizes ILOG Constraint Programming(ILOG CP(R)) optimisation software system to optimize and streamline matchscheduling. Using the new system, J. league have been able to shortenscheduling clip from three hebdomads to approximately one day. Optimalscheduling have enabled J. league to fulfill the demands of the teams, fansand supporters. The anchor of the J. league Match Scheduling System is ILOG CP, apart of ILOG's market-leading suite of optimisation scheduling softwarethat usages restraint programming techniques to let J. league executivesto instantly measure and compare respective options before deciding on a finalschedule. ILOG JViews(TM), visual image software system from ILOG, is used toprovide a more than visually-appealing interface for the system. ILOG CPsupports time-based constraints that let organisations to generateoptimal agendas with precise activity start-and-stop times. J. conference is a top professional football game (soccer) league in Japanese Islands andone of the most successful conferences in the Asiatic Football Confederation. Theorganization recognized a demand to automate and streamline its complex matchscheduling process, involving 33 squads and 79 schedules, with a sum of682 lucifers over a 10-month playing season. With no packaged applicationavailable for complex scheduling, J. league decided on a usage approachbased on optimisation engineering from ILOG. Optimization betters businessdecision devising velocity and efficiency by allowing organisations to calculatethe best use of existing resources -- in this case, squad personnel,stadiums and spectators. Before using J. league Match Scheduler, all lucifer programming for the J.LEAGUE was performed manually and therefore took on an norm two to threeweeks to finish owed to the complexness of the process. In deciding thecombination of lucifers and dates, schedulers needed to beguile manydifferent constraints. Such restraints include avoiding the programming ofa sequence of place games for a team, avoiding coincident place games ofteams sharing a place bowl or belonging to the same region, as well astaking into consideration states of affairs where bowls are not available dueto care or other seasonal restrictions. These restraints also changed each twelvemonth owed to the former year'smatch results, the addition or lessening in the figure of squads and specificrequirements of each team, increasing the complexness of programming evenfurther. With the former method of scheduling, the addition in the numberof squads was making it more than than and more hard for the schedulers tohandle. The new system was to guarantee a just agenda for all the teams,while taking into business relationship each team's specific requests, such as asavailability of bowls and possible struggles of agendas. Custom developed by ILOG, the J. league Match Scheduler, theproprietary lucifer programming software system of J. LEAGUE, now do it possibleto make agendas that are optimized to ran into the League's requirements,taking into business relationship the countless restraints that demand to be consideredwhen programming series of games for a given season. "Arranging a lucifer agenda for 33 squads while appreciated such as complexconstraints to the fullest extent possible necessitates a considerable numberof simulations, and it was almost impossible to make so manually," saidAtsushi Kawasaki of J. LEAGUE. "ILOG CP and ILOG JViews, which wereincorporated into the J. league Match Scheduler, have got provided agendas ofthe peak quality, while taking into consideration the basic schedulingrules put by J. league and the numerous person petitions of each team. Also, ILOG is able to supply a high degree of support to pull off the changesof the system needed to better the quality of our schedules. In additionto a flexible technical support to pull off the agenda development taskthat acquires more than than and more composite every year, we needed the highestperformance optimisation engineering available, which is why we selectedILOG."
